1'0 a-Z whom it iii-nay concern.-

Be it known that I, JULIUS W'ILHELM VON Plr'rLnmasubj ect of the Emperorof Germany, residing at Gohlis, Lcipsic, in the Kingdom of Saxony andEmpire of Germany, haveinvented an Embroidering Attachment forSewing-Machines,of which the following is a specification.

This invention is embodied in the following patents: German patent, No.39,491, dated December30,1885;French patent,N0. 173,692,211)- plied forJanuary 22, 1886, issued May 3, 1886; Austin-Hungarian patents, Nos.38,694 and 69,653, applied for February 15, 1886, issued February 5,1887; Belgian patent, No. 71,980, applied 'i'orFebruary 15, 1886, issuedFebruary 27,1886; English patent, No. 7,254, dated May 31,1886; Swedishpatcnt,No. 929, applied for Jo ne 1, 1886, issued September 2, 1887;Spanish patent, No. 9,581, applied for June 4, 1886, issued September27, 1.886; Danish patent, No. 788, applied for June at, 1886, issuedOctober 14,1886; Norwegian patent, No. 123, applied for June 8, 1886,issued October 6,1886; Italian patent. No. 20,554, applied for J one 22,1886, issued October 13, 1886.

My improvement consists in certain features of construction by which apantograph is adapted to an cmbroidering attachment for ordinarysewingniachines, as hereinafter described, and pointed out in theclaims. In anotherapplication, Serial No. 190,506,6led February 1,1886,1 have shown, described, and claimed another form of such embroideringattach ment for ordinary sewing-machines.

In order that myinvention maybe fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Figure 1 is a plan view of my improved embroidering attachment. Fig. 2is a plan view of a modification thereof. Fig. 3 is a plan View ofanother modification. 7

A is the cloth-frame supported in clampingjaws. To these clampingjawsare pivoted,at their inner ends, two links, a a, connected by pivots attheir outer ends to a bar, I), having a slot, 0.

c e and ff are the arms of inner and outer toggle levers, which areconnected at their i is a guide rail or plate, tg which the middle pivotof the inner toggle i lever is secured, adapted to be secured to thecloth-plate of a sewing-machine, having a slot, It, in which is pivotedthe middle pivot, g, of the outer tog gle-lever. The slotted bar I) andslotted guide rail or plate 1 permit the free and unim pedcd motion ofthe cloth-frame, thus keeping up a constantly-uniform relation of theparts a a, e e, and f f to each other. In this arrangement thepantograph B forms a part.

The arrangement of the attachment in Fig. 2 is substantially the sameasthat in Fig. 1, excepting that in this case the bar I) and inner toggleare dispensed with, thus limiting the extent to which thisarrangement-can be used, as the relations of the parts to each other donot remain equal whenever the outstroke of the point k of the pantographB is too great.

The arrangement of the attachment in Fig. 3 shows a lever mechanismarranged in the form of two perpendicularly counteractingparallelograms, G and D, in which the leg lot the parallelogram O isstationary, while the clamping-jaws are fastened to the leg 0 ofparallelogram D. Pantograph B is fastened above the parallelograms andpushes the clampingjaws by means of the leg oof the parallelogram D,according as the work requires.

The frame A consists of two frames or rin gsthe inner ring, 0', and theintermediate ring, q. The inner ring is quite smooth and simple.Theintermediate ring is cut or cleft and formed with a rough inside,andcan be drawn together by means of a screw, S.

pp are the spring clamping-jaws which on gage the frame A, and areconnected to the lever mechanism or to the pantograph.

The fabric to be embroidered is first laid on the inner ring and thenthe intermediate ring is pressed over it. Owing to the rough inner sideof the latter, it carries the fabric with it and draws it tight. Thering (1 is then drawn together by the screw S, and the rings thusconnected are jammed together wit-h the fabricinto the clamping-jaws,which are connected to the lever mechanism or pantograph.

I claim 1. An emhroidering attachment for sewingmachines, comprising acloth-frame provided with an inner frame or ring and an intermediateframe or ring, and a pantograph lever mechanism provided withclamping-jaws, substantially as described.

2. An embroidering attachment for sewingmachines, comprising acloth-frame provided with an inner ring and an intermediate ring, apantograph lever mechanism provided with clamping-jaws, and a guide railorplate adapted to be secured to the cloth-plate of a sewing machine,substantially as described.

3. An embroidering attachment comprising a cloth-frame provided with aninner plain ring, and an intermediate ring formed with a rough innersurface and having an adjusting JULIUS WILHELM VON PITTLER.
